Definitions

  • the present invention provides a DCCD loading device comprising: a shaft that extends from a tip end to a handle; a wire frame in contact with the tip end, wherein the wire frame comprises a plethora of wire loops extending away from the tip; and a film in contact with the tip end and extending over at least a portion of the wire frame.
  • the shaft comprises a shaft diameter of between about 0.25 and 1.0 inches.
  • the film comprises one or more polymers.
  • the tip end comprises a rounded tip.
  • the plethora of wire loops comprises memory metal.
  • the plethora of wire loops comprises nitinol.
  • the plethora of wire loops are attached to the shaft at the tip end.
  • the present invention is designed to aid in the positioning of a cardiac device about the heart.
  • the present invention may be used to implant a direct cardiac compression device or a cardiac compression device with a collapsible structure that assumes the shape of the left ventricle keeping an inwardly directed pressure to prevent the enlargement of the ventricle and provides adjustment of the end-diastolic volume for limiting/reducing the end-systolic volume.
